sbbuilder will not be able to help you on that one. If the package includes it's own (un)install scripts, that usually means as you found out, that it builds and installs using some other un-common method. sbbuilder works with standard things like autotools, cmake, python, etc. With that said, if you wish to install this anyway, you would have to use their scripts. Here are a couple of things to keep in mind.
Vector installs things to /usr/ not /usr/local/
The startup/shutdown scripts are in /etc/rc.d/ and the services stuff is in /etc/rc.d/init.d
Installation and removal of this package will not be supported by slapt-get or gslapt, so you'll have to manually remove it if anything goes south.
